Paper Abstract

This work presents the performance analysis of ring resonator-based tuneable optical filters, namely the influence of the design parameters such as coupling coefficient (k), coupler loss coefficient (a) and operating temperature (t) on the optical performance of the filter. Computed results have shown that a and k dramatically influences the performance of the add-drop filter, the operating temperature can effectively be used as a mechanism of selecting the desired frequencies within the dynamic range of the filter, and special attention should be paid to the operating temperature range of the filter in order to avoid a decrease of its free spectral range below the value of the desired pass bandwidth. Preliminary sensitivity analysis has also revealed that the single ring add-drop filter design is almost insensitive to the relative position of the two optical couplers onto the ring, and therefore very versatile for integration into a photonic chip.
